[ns] 802.15.4 and wired connections

[Chiraz Chaabane]

Hi,
 
I am trying to connect two different 802.15.4 PANs by using a wired connection within an hiarchical topology. Both coordinators are base stations. Messages transfer from one wireless node to a wired node works fine, but when i want to transfer a message from a wireless node connected to the first base station to another connected to the second base station, the first base station tries to forward the packet by using wireless medium. Any idea or suggestion please! 

Regards,
Chiraz
